Details

Woodpeckers® clamping accessory; the BC4-M2 Box Clamp is a simple device that eliminates the hassle of using heavy, expensive bar clamps for assembling boxes, drawers and especially full size cabinets. With the BC4-M2 Box Clamp, you can dry-fit and square up all your parts at the same time without any bulky clamps and before having to use any glue, screws or nails. You’ll know right from the start if what you are building will assemble to the final dimensions, be as square as you need or if minor trim cuts are necessary. You can do all of that without a second set of hands to hold pieces in place while getting a bar clamp in position and tightened up. And once your project is held together with the Box Clamps, you can immediately install any type of screws (even pocket screws) or nails because all of the corner joints are left fully accessible. There’s nothing to get in your way. No more struggling to get corners even with the uneven clamping typical of a bar clamp.The Box Clamps are designed for any 90° joint, including butt joints, lap joints, T-joints, miter joints, box joints, dovetails and more, even if material is extending past the face. Molded from a special combination of glass reinforced polycarbonate, the BC4-M2 Box Clamp is virtually indestructible and comes with hardware for both hand as well as fixture use. The clamp will accommodate materials from 1/4" to 1" in thickness. Made in the USA.

Includes 2 Blocks and 2 Knobs to assemble one corner

Reviews

Great clamps terrible packaging.

Great clamps, worked great holding boards for shelves, but the packaging imakes it difficult to unpack or return lol. Can be a little cumbersome aligning at first, has a tendency to lift panels when tightening, but I would buy more. Definitely holds in place when using pocket screws.

Great product but sold in a packaging nightmare

Great for assembling small projects. I use 4 to assemble drawer boxes.
Like others, I spent a LOT of time trying to remove the components from the package. I finally resorted to using a nail set and hammer. Whoever designed the packaging should do one more and then quit.
The printed instructions are not good and tend to make the product more difficult to use. Go to Woodpeckers website and watch the video for the Box Clamp.

Superior Customer Service

A freak thread separation on the main bolt that tightens the clamp caused it to jam in the nut. This happened on a brand new pair that I bought to add the ones I had already used for years. To get it apart I managed to strip out the plastic allowing the bolt head to now turn. The bolt was a simple 5/16 replacement but the little clamp piece was in bad shape. I called WoodPeckers and spoke to a great gentleman. No questions asked shipped me a complete set of replacement parts. Even the handle. WOW!! Try that with your cheap import manufacturer... I remain a very satisfied customer.

Very handy and simple clamp

What a terrifically simple to use clamp. I saw a video for these on YouTube and saw them at the local Woodcraft. Glad I picked them up. Holds at a true 90deg while screwing or letting glue set up.

works well

These work great for holding together shelves for fastening together. Relatively easy to use and figure out. The PACKAGING needs to be reworked - it took me a half hour and tools to get them out of their packaging!

Can't Work Without It

Using these clamps is easy and they help align pieces almost perfectly square. they are easier to use than pipe clamps and eliminate the need for a second set of hands on a project like my most recent-- building four separate bookcases.

Gift for my husband. Exactly what he needed to finish a project for our grandsons.

Nice Jig but wrong bolts

As description says they are for box building but not large boxes such as cabinets. They help with basic alignment of large project so ok when working by myself..
My complaint is that the bolts that you adjust the moveable portion of the clamp are too long. They stick below the bottom of the clamp (about 1/4") when you tighten for dimension of lumber, so that the jig will not sit level on the table/floor.
I live in a small mountain town with one hardware store. No replacement available locally. Went to a larger town about 45 minutes west. No luck. A week later went to a town an hour to the east. Nope. Finally found the correct bolt & pitch a quarter of an inch shorter in Charlotte when visiting my daughter. Even then it took visiting 3 stores (hardware & auto).

Good Clamp; Asinine packaging

The product is cleverly designed and easy to use with material up to 3/4". On the other hand, the packaging is a marvel of marketing over common sense, with plastic attachments that variously must be pried or screwed to release the clamps and knobs for use. The box says "Made in USA," but I suspect the packaging was designed in Transylvania by . . . .
